I recently ordered new parts and I'll have them in on tuesday. I chose the AMD Phenom II 955 Black Edition, should be more than adequate and it should overclock to 3.8Ghz with good stability. I also bought a new case, an Antec Three Hundred. Should be less bulky than my old Antec server chassis. My old PSU will not suffice because it doesn't even have SLI power connectors, so I bought a 650W Antec. I bought one 250GB SATA hard drive, with intentions of buying two or three more for the purpose of raid0. For ram, I have ordered 4GB's of DDR3 PC12800, also with intentions of buying another set in the future. My brother dashed me his old 8800GTX, which should be adequate, and possibly more so when I buy a second for SLI. I think this system will be pretty potent, especially considering that I only spent $600. I am hoping this setup is somewhat future proof with the AM3 socket and DDR3 ram, time will tell. I am giving Windows 7 a shot, with a dual boot of XP. I read a few reviews of my MSI motherboard having burn-in failures, wish me luck so I don't get a bad one.
